APPARATUS FOR CARBURETING GAS.

SPECIFICATION forming part of Letters Patent No. 347,663, dated August17, 1886.

Application filed February 6, 1886. Serial No. 191,0(1'2. (No model.)

To all whom it may concern.-

Be it known that I, JONATHAN S. TIBB Ts, a citizen of the United States,residing at Jeffersonville, in the county of Clarke and State ofIndiana, have invented new and useful Im provementsin Apparatus forOarbureting Gas, of which the following is a specification.

This invention relates to a gasanachine, or an apparatus for(-arbureting air or gas for heating and illuminating purposes, or foruse as a motive power; and it consists in the construction andcombination of parts, as hereinafter set forth, and pointed out in theclaims.

The invention is illustrated in the annexed drawings, in which Figure lis a vertical Teentral section, of my improved gas generator orcarburetor. Fig. 2 is a section on the line was of Fig. 1, viewed fromthe under side of the apparatus, and showing a plan of the convolutedpassage in the lowest carbureting-chamber. Fig. 3 is a bottom plan viewof one of the upper horizontal partitions forming the floor and roof oftwo adjacent chambers. Fig.

4 is a perspective showing the upper surface of one of said partitions.

Referring to these drawings, the numeral 1 designates a tank, preferablycylindrical in form,and composed ofcopper, galvanized iron,

or other suitable material. Near the bottom of this tank is anair-inlet, 2, having a cock, 3, and near the top is another air-inlet,4, having a cock, 5. These airinlets consist of horizontal pieces ofpipe, preferably connected by a vertical pipe, 6, having a branch, 7,that leads to a pump or other apparatus forforcing air or gas into thecarburetor. Near the .bottom of the tank 1 is also located a venttube,8, provided with a cap, 9, or other stop- The tank 1 is provided with aclose-fitting conical cover, 10, having a fillingtube, 11-, located nearone edge. This filling-tube may have a cap, 12, or other stopper. Atanother point near the edge of the cover .is located a vent-tube, 13,provided with a cap, 14, and from the center of the cover a gas-deliverytube, 15, rises, by which the carbureted gas can be conducted to asuitable reservoir or to the place of consumption. This gas-deliverytube 15 may be provided with a cock, 16, at any desired point.

.Within the tank 1 is arranged a series of horizontal partitions, 17,cut away alternately on opposite sides, thereby forming a series ofcircuitously communicating compartments or chambers for reception of thecarbureting-liq uid, and in these chambers are formed convolutedpassages 18 for the air or gas to be carbureted, whereby the course ofthe air or gas through the carbureting apparatus will be somewhatretarded, so as to cause it to remain in contact with the carburetingmaterial for a sufficient period to produce a good quality of gas; Thehoriz'ontalpartitions 17 are each circular in form, except that they arecut away or reduced in diameter on one side, as shown in Figs. 2, 3, and4, and their curved edges are formed with a slight upwardly-bent rim,19, which affords a hold for the solder, rivets, or other fastenings bywhich they are secured to the wall of the tank. These horizontalpartitions 17 thus form a series of communicating carbureting-chambers,in each of which, as before observed, is arranged a convoluted passage,18, for the air or gas to be carbureted. Each carbureting-chamber isalso provided with a radial passage, 20, and these radial and convolutedpassages are preferably made by attaching depending metallic plates 21of proper form to the under side of each partition 17, as shown in Fig.1.

1n the bottom car bureti ngchamber the outer end of the radial passage20hasits sides flared slightly, as shown in-Fig. 2, and terminates at thelower inlet, 2, the slightly-flared outer end of said radial passagebeing secured to the 'wall of the tank on each side of said inlet. In

the ends of which are slightly flared or bent,

.as shown at 24 in Fig. 4, to facilitate attachment to the tank-wall,and also to close the ends of the spaces between said flaring lips andthe adjacent flaring ends of the radial passages. These vertical lips 23are each of less height than the carbureting-chambers, and consequentlythere is formed above each lip a horizontallyelongated opening, 25,through which the several chambers communicate.

It will be observed by reference to Fig. 1 that the partitions 17 andlips 23 are so arranged that the several carbureting-chambers communicate alternately on opposite sides of the tank, thus affording acontinuous circuituous passage from bottom to top. The top horizontalpart tion is removable, and has no upwardlybent rim and no lip. It is,however, cut away at one side, like the other horizontal partitions, andthis cut-away portion of said top partition is arrangedimmediatelybeneath the filling-tube 11, through which the apparatus is suppliedwith gasoline or other earburetingliquid.Thecarburetingliquidintroducedinto the tank 1, through the fillingtube11, enters the upper carbureting-chamber by way of the opening 22 at theside of the top partition, 17. It then passes through the convolutedpassage 18 toward the lip 23. \Vhen the carburetirig-chamber is filledto the level of the lip 23, the liquid overflows through the openings 25and 22, and thus gains access suecessively to the chambers below. Inthis way all the carbureting-ehambers are sup plied with gasoline orother hydrocarbon liquid, which liquid rises in the lowest chamber tothe level of the vent S, which is then closed. After the earburctorhasthus been charged and made ready for use, gas will be generated byadmitting atmospheric air through the lower inlet, 2, said inlet beingin communication with anysuitable air-forcing apparatus. On eon1-mencing to force air into the earbureter, the.

upper vent, 13, must be closed. The air forced into the carburetor flowsthrough the circuitous passages of the several chambers over the surfaceof the gasoline or hydrocarbon liquid contained therein. In each chamberthe course of the air is inward through the radial passage 20, thenceoutward through the convoluted passage 18, and then upward by way of theopenings 22 and 25 to the radial passage of the next chamber above.

The space between thetop horizontal partition, 17, and the conicaltank-cover 10 forms a receiving-chamber, 26, in which the gasaccumulates before passing to the delivery-tube 15, the vent 13 andfilling-tube 11 being closed.

As before remarked, the air-inlets and the gas-delivery tube may beprovided with cooks for confining the gas within the carburetor,andpreventing waste when the gas is not in use.

It will be observed that the circuitous passage-way or air-conduit ispartly formed by the walls ot'the tank, within which the severalpartitions are closely fitted in such a manner as to avoid leakaget'romone chamber to another. The air or gas admitted to the carburetoris thus compelled to pass in a finely-divided current over the entiresurface of the hydrocarbon or other carbureting fluid contained in theseveral carbureting chambers. By this means the air or gas undertreatment soon be comes thoroughly charged with hydrocarbon material,thus producing a rich and highlyvaluable quantity ot'gas, suitable forall ordinary purposes.

In some cases, where the gas contains too much carbon, it is desirableto mix with it an increased supply of oxygen before it is delivered fromthe carburetor. For thispurposeI have provided the upper air-inlet, 4,which communicatesdireetly with the radial passage 20 of the uppercarbureting-ehamber. This upper air-inlet, his prcferablya branch ofthemain supply-pipe, as shown, and has a cock, 5, which should be closedwhile the apparatus is being filled with gasoline, and also when it isdesired to introduce air through the lower inlet exclusively.

It is apparent that by means of the upper and lower air-inlets thequality of the gas can be readily controlled.

This gas generating and carbureting apparatus combines the advantages ofsimplicity, etlicirncy, and economy with compactness of form, and therebeing no waste spaces in its structure itat't'ords alarge carburetingsurl'ace, while at the same time it occupies but little IOOlll.

\Vhat I claim as my invention is- 1. In a gas generator and carburetor,the combination, with a tank having an air orgas inlet, a filling-tube,and a gas-delivery tube, of a series of horizontal partitions, 17, eachreduced in diameter on one side, and formed with a slight upwardly-bentrim,19, for attachment within the tank, said partitions being providedon their upper sides with vertical lips 23, having flaring ends 24, andon their lower sides with vertical plates 21, forming convolutedpassages 18 and radial passages 20, substantially as described.

2. A gas generator and carlniretor consisting of a tank having at thebottom an air or gas inlet and a vent and at the top an air or gasinlet, vent, filling-tube, and gas-delivery tube,and a series ofhorizontal partitionsaltcrnately reduced in diameter or cut away on opposite sides, and provided on their uppersides with vertical lipslocated at said cut-away portions, and on their lower sides withvertical convoluted plates forming convoluted and radial passages, saidplates being secured within the tank to form a vertical series ofcarbureting chambers communicating alternately on opposite sides,substantially as described.

In testimony whereof I al'tix my signature in presence 01' twowitnesses.
